SFT-40 Silicon Rubber Self-Fusing Tape
Descriptions
HarshMet SFT-40 self-fusing silicone rubber tape is a high temperature and arc-and-track resistant tape composed of self fusing, inorganic silicone rubber and easy-tear and easy-strip liner. SFT-40 has wide
temperature tolerance of -50 to 250 . It can be
applied through 15kV for insulation and sealing for cable and reenter connections.
